PEDESTAL-GI]; FOR AXLE-BOXES.

Specification of Letters Patent. 7

Patented Dec. 29, 1908.

T 0 all whom it may concern:

Be it known that I, SAMUEL M. VAUOLAIN, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain improvements in Pedestal-Gibs for Axle-Boxes, of which the following is a specification.

My invention relates to certain improvements in pedestal gibs or guides for axle boxes, the invention being particularly adapted for use in connection with the boxes of the driving axles of electric trucks, although it will be understood that the invention may be used in retaining any form of box to its pedestal or hearing.

The object of my invention is to so desi n the mechanism that the box can be readi y removed from the pedestal of the truck without requiring the pedestal to be raised.

This object I attain in the following mannor, reference being had to the accompanying drawing, in which I Figure 1, is a side view showing sufficient of a truck frame and box td illustrate my invention; Fig. 2, is a sectional plan view on the line 2-2, Fig. i; Fig. 3, is a perspective view of one of the gibs detached; and Fig. 4, is a view showing the location of the gibs in respect to the frame prior to the removal of the box from the frame.

A is the truck frame having pedestals a, a. B is the box in which is mounted the axle 1; this box can be of any type desired and is grooved at each side I), 12 forming flanges 1) between which are mounted at each side the gibs D, 1); those gibs are flanged at d, d so as to extend on each side of the pedestals moi the frame A. The pedestals are cut away al (1 and the length of the upper flange (Z is less than the length of the cut away portion (1., so that when the gills D are dropped to the position shown in Fig. 4 they can be readily 'removcd laterally, the upper flanges (l passing through the recess a formed by cutting. away the pedestals E is a bottom picco connecting the lower ends of the pedestals, the bottom piece being notched at c; cto engage projections on the frame A and this bottom piece holds the gibs l) in position.

(l is a coiled spring which rests in a cavity 6* in the upper portion of the box and is hold in )osilion by a stud of )ro'ectin from the upper portion of the frame.

When the parts are in the position shown in Fig. 1, it is impossible for the box B to move laterally, as the flanges on the gibs D, D engage the pedestals of the frame and project into the grooves in the box, but when 1t is desired to remove the box all that is necessary is to relieve the pressure on spring G and detach the bottom plate B, allowing the gibs D to drop to the position shown in Fig. 4, in which position their upper flanges are in line with the recesses .t in the pedestals, and when in this position the box can be laterally removed with the side plates without raising up the truck.

hen it is wished to assemble the parts the gibs are placed in the grooves in each side of the box and the three pieces then slipped-intoposition, the flanges d passing through the recesses a in the edestals, after which the gibs are raised and the bottom )late E secured in position.

1. The combination of a framehaving recessed pedestals, a journal box nlounted between the pedestals, gibs engaging the journal box and having flanges overlapping the pedestals, said flanges being cut away so that when moved to a certain )OSltlOIl the journal box and the gibs can e removed laterally from the frame. 4

2. The combination of a frame having pedestals, each recessed on the inner side, a journal box recessed on each side, two gibs mounted in tin recesses of the journal box and having flanges cut away at the. center,

and a bottom plate secured to the frame and adapted to hold the gibs in position.

3. The combination of a frame having pedestals recessed at the center, a journal box recessed on each side forming flanges, two gibs mounted on each sidc'of the journal box and adapted to rest between the flanges, said gibs having flanges cut away at the center, the upper section of the flanges being less in width than the recesses in the pedestals so that the box with its gibs can be laterally removed from the frame.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
